Use logic and reason instead ... those little things everyone has forgotten about or twisted into something far from what they should be. It's never ok to use nuclear weapons for many many many reasons ... radiaton, mass death and destruction, mutations, contamination of food and water sources, tons of money wasted cleaning up the shit. War is never ok either, but hey can you stop it ? Can you convince everyone to put down their weapons and stop the madness ? Do you care to ? I don't, they made their own bed, now they will sleep in it.
P.S. One of my theories (one of the wierder ones) on this is as follows:
All people on this planet are guilty of the acts anyone commits ... collective guilt. If your neighbor commits a crime you and everyone else on this planet is as guilty of it as the neighbor himself. Why ? Because you allow it to happen ... you don't stop it ... you don't prevent it ... you live with it
Also note that at times I seem to contradict myself ... well, you're right I do, because I don't always express my personal point of view in what I say ... just making an argument, seeing if it holds water, if it does, keep it ... if not, discard it
